What are the ligaments that hold the glenohumeral joint together? Watch and learn in today’s episode.
Transcript of Today’s Episode
In this video, I’m going to be talking about the ligaments of the glenohumeral joint. Let’s get right into it.
If you remember, the glenohumeral joint is what you see in this picture, specifically right here, where the glenoid fossa and head of the humerus, where they’re articulating with each other, basically, the humerus articulating with the scapula.
We have a number of ligaments that are involved in holding them together. What are those ligaments?
The first ligament that I want to talk about, it’s indicated here as the capsular ligament. That’s kind of all the way around, really. It’s a set of ligaments that we call the glenohumeral ligament. Here, it’s indicated as the capsular ligament. That’s the first one. It’s giving support on the anterior aspect, and also on the posterior aspect of this glenohumeral joint.
The next one I want to talk about is the one that goes from the coracoid process down to the humerus. That would be the coracohumeral ligament. That’s this guy right here, the coracohumeral ligament.
Then, we have another one that helps to reinforce this joint. That’s the one that goes from the coracoid process to the acromion process and that’s the coracoacromial ligament.
Lastly, we have one more that traverses between the greater and the lesser tubercle. That is the transverse humeral ligament that you can right here. You can’t see it on here, but you can see it here. Here, it would be right extending here but it’s not in this picture. That’s the transverse humeral ligament.
Brief review, here we have the glenohumeral joint, and you can see we have the glenohumeral ligament or the capsular ligament that reinforces the anterior and the posterior aspect surfaces of the glenohumeral joint. We have the coracohumeral ligament right here, and then, we have the coracoacromial ligament, and also, it’s not shown in this picture. I should have used the other picture here. But, there’s a ligament that goes across from the greater tubercle to the lesser tubercle, that’s the transverse ligament.
